(Yuji couldn't do anything, you were dying and he couldn't do anything. The curse the both of you were fighting managed to catch you off guard and land a fatal blow.)

(Yuji had to witness it all. He exorcised the curse and ran over to you, but he couldn't do anything. You are slowly dying in front of him.)

I-I, DON'T DIE ON ME PLEASE! I'LL FIND A WAY TO HELP YOU, I SWEAR YOU'LL BE OK. (Yuji said.)

(Yuji knew there wasn't anything he could do, he was just gaslighting himself at this point.)
